Sorry, but the average Firefox nightly build (trunk or branch) is decidedly less stable (both in terms of crashes and in terms of things not being broken_ than the average 1.7 branch nightly build, from what I can see of the bug reports.

That's a direct corollary of the fact that major work is happening on both trunk and aviary branch and no such work is happening on the 1.7 branch, mind you.
